Specification of Letters Patent.

Patented May 7, 1907.

Application filed November 11,1905. Serial No. 286,955.

To all whom it may concern.- 7

Be it known that I, CHARLES J; TROPPMAN, a citizen of the United States, residing at Marquette, in the county of Marquette and State of Michigan, have invented certain new and useful Improvements in Adjustable Means for Attaching Lenses, of which the following is a specification.

My present invention relates toimprovements in adjustable means for attaching lenses, and has special reference to the provision of a simple article which will provide a strap or lug 011 each side of the lens and a lens seat capable of adjustment to accom modate different thicknesses of lenses.

It will be perceived that in my design any form of strap or lug for securing attachment to the lens may be employed while the ad justment for different thicknesses of lenses is secured through the lens seat or body connecting the straps or lugs aforesaid.

I employ my invention in one of its forms in my one piece mounting for which I have prepared and executed an application for patent of even date herewith.

To the securing of the above objects and results the invention consists of the new and novel features and combination of parts as Wlll presently appear.

In the drawings :Figu re 1 is a plan view of a stamping of my improved lens attachment in a form applicable to one piece mountings. Fig. 2 'is a perspective view of the stamping shown in Fig. 1 bent into shape and with lens in position. Figs. 3, 4, 5 and 6 illustrate various attachments which may be made. Fig. 7 illustrates a modification of my invention made from several pieces instead of a single stamping. Fig. 8 illustrates my lens attachment in connection with a bridge or nose piece. Figs. 9 and 10 are modifications of my invention showing one piece stampings particularly adaptable to the attachment of temples or other accessories to the lens. Y Referring to the drawings the numeral 1 wrlesignates a strap or arm whlch makes conlie Q7." with the mounting or instrument.

The il'lmeral 2 designates that part of the metal which forms the lens seat having the aperture 3 provided in its central portion. From substantially opposite portions of the lens seat 2 extend the straps or lugs 4.

In Fig. 1 I utilize a portion of the metal which has to be removed to provide the aperture 3 to form one of the straps or lugs 4. After the stamping has been formed the straps or lugs 4 are bent at right angles to the lens seat 2 and the proper adjustment is secured by compressing the lens seat 2 until the desired separation between the straps or lugs 4 is secured. It is also obvious that the lugs 4 can be separated by distending instead of compressing the lens seat 2.

It may be found in manufacture that it is desirable to construct the lens seat 2 of more than one piece of metal either solidly jointed together or pivoted to permit of easy adjustment.

The lens attachment can be made in almost infinite design for ornamental purposes applicable to reading glasses, magnifiers, etc.

Figs. 3 and 6 illustrate the application of my lens attachment to temples for spectacles. Fig. 6 shows a form in which nothing is visible from the front except one of the lugs 4 and an edge view of the lens seat 2.

Figs. 4 and 5 show forms of attachment which may be employed to form studs for eye glasses.

It is obvious that I provide a lens attachment of extreme simplicity both in manufacture and final form which has extreme rigidity and neatness and is capable of easy adjustment to various thickness of lenses.

I-laving described my invention, what I claim as new and. desire to secure by Letters Patent is 1. A lens attachment consisting of an adjustable lens seat having a centrally located aperture, and straps for engaging the lens and the mounting extending from the inner and outer peripheries of said lens seat.

2. Means for attaching lenses consisting of a member from the central and edge portions of which are produced straps for securing the lens and for attachment of the mounting.

3. Means for attaching lenses consisting of a lens seat, adapted to lie adjacent to the periphery of a lens, and straps, adapted to engage the lens and the mounting for the lens, produced from the central portion and outer edges of said lens seat.

4. Means for attaching lenses consisting of a member having a centrally located aperture, straps, for the engagement of the lens and the mounting for the lens, carried upon the inner and outer edges of said first-mentioned member.

5. An adjustable lens seat having a central aperture and means for its attachment produced from the inner periphery thereof.

6. A lens attachment consisting of a lozenge j pendently adjustable parts.

In testimony whereof I aflix my signature shaped structure having a central lozenge in presence of tWo Witnesses.

shaped aperture and means provided upon the suitable interior and exterior angles of said structure for its engagement.
